How do inscriptions help in writing …

Inscription helps alot when writing the history of the Gupta period because with the help of it we can trace from it earliest period to its last period. Here are some of the example:
(a) Dr. Fleet rendered great service by publishing in 1888 the third volume of Corpus inscription of the early Gupta kings and their successors.The first 16 inscriptions in the above mentioned corpus refer to the early Guptas.Their dates range from 360 A.D. to 466 A.D.The date line of the early Gupta dynasty is taken to end with Skandagupta.
(b) ;The Allahabad pillar inscription of Samudragupta gives us a detailed account of the conquests of his.
 (c) ;The Eran Stone No. 2 inscription of Samudragupta’s period contains a record of the power and achievements of Samudragupta. 
(d) The Udayagiri cave inscription, the Mathura stone inscription, the Sanchi stone inscription and the Gadhwa Stone Inscription of the time of Chandragupta II give us a lot of information regarding the attitude of the state towards religion.
Thus we can see from the above example that the inscription touches almost all the aspects of the Gupta rule. From its economy, society to political. Thus making it easier to reconstruct many aspects of theri rule from first Gupta ruler to the last one.
